you know firestone is an authorized tire rack installer,in fact most big companies are,you should really take the time and just go in and talk to some techs,your making this wayyyyyy harder than it needs to be,we have all installed tires and wheels much more delicate that what your wanting done. Who in there right mind pays for shipping wheels and tires so they can get them mounted? try any Firestone for aprox 65 dollars we mount all 4 and balance,if we screw it up we will take care of it, and we even offer lifetime balance
